First, if we have three different notations, why this one should be
preferred as the default one?

Second, from `-------' to `-rw-rwxr-x', there is 5 times `space' and
three `right' when we talk about toggling, while it's `right, C-d, r,
C-d, w, right, C-d, r, C-d, w, C-d, x, C-d, r, right, C-d, x' when
editing, which is a lot more cumbersome.  And typing `-rw-rwxr-x'
(which, you'd agree, is not natural) is best replaced by `a+r,ug+w,go+x'
or `675' if you're bit-oriented.  The `ls -l' notation has the drawback
that you have not only to precise the modes the file have, but also the
modes the file doesn't have.

But of course, if there're people that actually want to use that, we can
add it I guess.
